Rapid Bike Evo install - best location for controller unit

[SteveW19]

Picked up the Evo system at the NEC show having read good reports on it. The manufacturer suggest placing the control unit under the steering head using a bracket, which is ok but I use that space for an after market horn currently, so I wonder if anyone has already found alternative locations? Bike is a 2018 GSA

This is a big job.
Tank & all bodywork off job.
The loom has to cross over the bike and there are some fiddly plugs to reach.
They recommend down near the engine but i didn't like that and put it at the back of the bike where I could access it.
I also bought the bypass dongle plug, just in case I had a problem with it.

i don't have the Evo, but i placed my Easy unit here (it no longer fits under the seat due to the Corbin basepan):
Enjoy the mod...the rapidbikes are great pieces of kit!

I understand that the OP ask for the best location of the Rapid unit, thus my question may be a bit off topic. However, as my questions relate to the Rapid units, I take the liberty to ask anyway:

From the looks of it, the units seems to be well built. But as I googled for where to order, I could only find adds for the pre LC bikes.

Is there any units that are made to work with the 1200LC engine with Euro4 software?

The EVO unit advertise adaption capability. Why would we order the EVO unit rather than the Easy unit? The BMW ECU is adaptiv already, so why pay extra for a feature that is already installed in the bike?


The Easy unit appear to be an alternative to the AF-XIED, and it is able to handle two O2 sensors. But I could only find units for pre LC engines. Does anyone know if Rapid has made a modified Easy unit that is capable to handle the Euro4 software in the LC?


Any one in here that use the Evo or Easy unit on their Euro4 LC and know for sure that the ECU does not throw a faultcode (it not visible without a code reader)?

I use the Easy Module on my GSA LC 2014. No VISIBLE fault codes (unless you hook up a GS911 and look for lambda fault/codes)

Here is a link to the LC model Rapidbike:

If you want to confirm that the KRBEA-017 model fits our LC´s, you can contact Dimsport directly [email protected]
They are very helpful and will also help with trim settings (should you want to play with them, which i found unnecessary...)

The link leads to a page with a generator that shows what bikes are compatible. Seems to stop with the pre -16 bikes. 2016 was the year Euro 4 was introduced.

A shame really if that is the case. If I understand correctly, the "Easy" unit does the same job as the AF-XIED, but with one single box only. (thus, less than half the price)

I'll wait a while and see if it works on the 1250, which will be my companion for the next couple of years..

What does it do and why do I need one?

It's probably easier to take a trip to Hinckley.

By all the reports, you probably won't need it on the 1250!

I may have misunderstood this, but from what I have read I think BMW introduced extra checks on the O2 sensors when the bike switches on and these fail when the EASY or AF-XIED units are fitted. I think someone was developing new hardware/firmware for the AF-XIED units so that the bike would see the O2 sensors during its checks but then control of these would be taken over by the AF-XIED unit after the checks were passed. Not sure what progress has been made on this.

What you are saying is all correct. However, I have yet to see an engine that does not benefit from a slightly richer than 14,7 AFR.

I have done a bit of research in this area as I built my own manipulator for my present -15 GSA (at a time when the AF-XIED did not work). I made it work, also after my bike got upgraded with the Euro 4 software. As such, I would therefor not need to buy a unit. Even so, DIY work is quite time consuming, so if a working unit is available for £150 it is tempting to save lots of work.

Like you say, the AF-XIED got a modification to make it possible to work on the Euro 4 engines. But in the usual American way (and no offence to our US friends), they are reluctant to modify a already working item. The first fix was a separate box with a relay that delays connection of the O2 sensor in the beginning (I've seen suggested 10 sec. delay), thus you needed 4 small boxes. Then they integrated a relay, so, now you are down to two boxes. Still, the Rapid unit handles two sensors, which is far more elegant. The only catch is, it seems not to be working on Euro 4.

As suggested, the 1250 is reported to be smooth, as may be said about the Euro 4 software for the latest 1200 LC engines as well.

As for my own -15 engine, it did pretty well prior to the Lambda manipulation as well. The manipulation did not offer a whiplash experience, but the engine felt more responsive when opening the throttle and generally ran even sweeter It is therefor very tempting to see what a manipulation will do to the 1250...
